Whenever a vehicle battery has to be dis-connected, switch off all equipment,
interior lights etc, close the doors leaving the drivers window open.
Switch off the ignition and remove the key and any DIAG equipment.

Wait a full 3 minutes before disconnecting the battery.

The BSi must be allowed to go to SLEEP i.e. into "power save mode". Do not
operate any equipment on the vehicle during this time. Remember, even
opening the bonnet will wake the BSi on a vehicle fitted with alarm.

If the battery is under the bonnet, open the bonnet first and leave it up. 807
batteries can be dis-connected through the drivers window, remove floor cover
first. (note, Pics are under the passenger seat)

ALWAYS disconnect any DIAG equipment and do not operate any plips from
other vehicles during the 3 minute waiting period.


PROCEDURE FOR BATTERY RECONNECTION
Unless otherwise instructed by Product Service, you must always
carry out the following procedure, often referred to as a "soft re-boot", to
minimise the possibility of the BSi corrupting its own software when
reconnecting the vehicles battery supply.
Ensure the procedure for battery disconnection has been adhered to and
importantly all BSi functions were switched off with the drivers window left
down.
1 Close all doors
2 Remove ignition key if left in ignition
3 Reconnect battery. DO NOT open any doors
4 Wait 10 seconds
5 Switch on headlights through the drivers window (you will hear a "bong") (note: Snap-on says Side-lights)
6 Switch on ignition then start the vehicle and check system functions

NOTE: Upon reconnection, if any vehicle function controlled by the BSi i.e .
interior light is switched on,the internal operation of the BSi has the potential
to spike or corrupt its configuration and software program......

Found this additional info in regard to the 607...
I hope this info is accurate and useful...
If not - please let us know :)

Remarks and Special Points
607 Vehicles
607 vehicles can have two batteries. The second battery is located in the boot under the R/H/S boot trim. This battery
powers all the vehicles systems. The front battery is for starting only. a single red 50 amp maxi fuse, located to the left
of the engine management ECU, connects the second battery to the vehicle. This fuse must be removed as well as the
front battery connection to disconnect battery power on these vehicles. There is also a maxi fuse at the battery end
under the boot trim. This is not accessible without removing the trim but the connections to the fuse holder should be
checked if power is lost to the front of the vehicle.

Id just like to add on all what betty said:

If vehicle if fitted with alarm and/or bonnet switch, lifting the bonnet up and leaving it that way will keep the bsi in awake state. and once you reconnect power it will wake up immediately because the switch is still open.

i had to tape my switch into depressed position so bsi wouldnt wake up when i was measuring current draw on my 407. hope this makes sense! :)

3 Minute Rule

I have a slight problem with the 3 minute rule. My car is not in front of my own house so I can't wind the drivers window down and leave it open overnight. Can I just open the driver door and bonnet and wait 3 minutes? Just as long as I dont close the door until I've removed the battery??

Or tape in the button on the door to fool the bsi that it is closed?

Thanks :)

To add to this. My car is fitted with a tracker. This is connected via ignition switch and also constant live. Leaving the car 3 mins still has no affect on the tracker which is keeping the car awake due to the constant live. I had to remive this to change my battery. So heads up anyone with a tracker or any other live equipment like subs and head units

Yes I've seen this list on another site where indeed it says "side lights" - I tried that in the hope it might reset the central locking - key fob RF thing. This 206 is a bit frustrating with open this, press this for 2 seconds, open door, comb hair, stand on one foot, then turn ignition on.

Anyway apart form that, all info is good.

EOBD Memory Saver

Hi all,

Could you not instead use an EOBD memory saver ?
This plugs into the 16-pin EOBD diagnostics port and allows removal of the vehicles battery without losing any codes or settings and leaves your ECU energised.
Then you don't have to worry if you have followed all the correct procedures.

You do however need the use of a slave battery and the device itself costs just over £20.

Just seen this, so I checked with the SEDRE for my 206, and yes, it will keep the system live whilst the battery is disconnected, but you must not switch anything on in the car, or the fuse may blow and cut the supply.

£20 seemed a bit over the top, so I checked eBay - lots of choice. Here's one for only £5.69.

Sorry for the late reply Ian, just noticed this in my inbox, mine is made by Draper so probably paying for the brand name, there's not much to them really.
A bit confused about the fuse blowing part as with battery disconnected there is no current available for blowing fuses. Still best not to switch anything on, why would you want to ?

The source of current would be the 12V supply you provide to the croc clip leads.

I must admit I can't think of any reason to switch anything on, but doubtless Murphy's law applies :)

Forgive my ignorance, but what is a BSI? Has anyone compiled a glossary for the technical abbreviations used on this site? It could be useful for a greenhorn like me!
